Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

follow-up-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Follow-up Writer

Overview

Turn a brief note about a hallway conversation into a short, warm, specific follow-up the employer can send within 24 hours of the event.

When to Use

Use when the user says they met someone and wants to follow up, reconnect, or stay in touch.

Workflow

  1. Identify: who they met, where, what was discussed, and the goal of following up.
  2. Open with one concrete callback to the actual conversation (not "great to meet you").
  3. State one clear, low-friction next step (a call, a coffee, a shared link).
  4. Keep it under ~120 words. Output a subject line plus the body.
  5. For any missing fact, insert a [placeholder] — never invent it.

Output Format

Subject: <short, specific>

<2-4 short paragraphs, ready to paste>
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
